Is it possible to enable horizontal scrolling for the tree? Right now I have nodes nested very deep and could use to be able to enable the hScroll for the tree. Also, is it possible to adjust the textsize somehow?

I originally designed Data Tree around being just a tree control for Mac OSX and for some reason after adding support for the other platforms, never actually added a horizontal scrollbar.

The publicly available version doesn't have adjustable font sizing but I can either build you a bespoke version with font settings of your choice or supply you with a beta of the new update I've been working on, which allows you to customise pretty much everything.
